Imagine a construction site where 500 workers labor for an entire year without one Occupational Safety and Health Administration (OSHA) Recordable injury?  That is roughly what it takes to go one million workhours without such an incident. It is an achievement attained by several ARTBA members – and some have earned it several times!

The ARTBA member firms listed below were recently recognized by the National Academy of Construction (NAC) for their outstanding achievement.

In 2011, NAC recognized 23 construction companies in North America that surpassed the one million-workhour mark with zero recordable injuries.  During the past eight years, the organization has added 91 additional achievers for a total of 114. Twenty-eight of these record-holders have earned over two million hours, nine for over three million, and three for over four million workhours free of OSHA recordable injuries.

The first known construction contractor to exceed one million hours worked with zero OSHA recordable injures was ARTBA member Zachry Group of San Antonio, Texas.  Since then, there have been 196 other occasions where one million hours free of OSHA Recordable injuries have been reported.

The following ARTBA members were recognized by NAC in 2019:

Ames Construction

Burns & McDonnell

Flour Corp.


Kiewit Corp.

Superior Construction

Zachry Construction

Zachry Group
